------- Comment #1 from amylaar at gcc dot gnu dot org 2006-05-02 17:53 -------
In 3.x, double -> char/int conversion was done consistently with the documented
behaviour of integer -> signed integer type conversion.
http://gcc.gnu.org/onlinedocs/gcc-4.1.0/gcc/Integers-implementation.html#Integers-implementation.
In 4.1, fold-const.c:fold_convert_const_int_from_real implements java
semantics.
I think for consistency, when folding a floating point value to an integer
type of smaller width than integer_type_node, it should be converted to
integer_type first, and then from there to the target type, using the
language-specific semantics.
